Be it known that I, PAUL H. fDAsEN, a

citizenof'the United States, and a resident i 'ofGttosen7 `in thecounty rif-Humboldt and State of Iowa,-ha ve invented a certain new and usefulY Steering Rod Controlling'v De# vice, o fwwhich the following is a specica# 1 tion.

Y The ect of my invention is toprovide a steering rod operating device ofsiinple, and

inexpensive construction, whereby ya steer- Y parts of the device, wherebythe objects corr.`

ling rod on atractorma'y be operated away from and located at a point spaced from the tractor, said devicebeing so constructed as to allow play'between the ytractor and the other'machinerywithout a-ii'ecting the control 'which the Aoperator has on the` steering' rangement and combination of the various templated are attained, as hereinafter more fully set forth, pointed" out yin myy claims and illustrated in the accompanying draw- .e ings, inwhichz"v Figure 1 shows a vention.

Y' VIn' haulingfa binder or other piece of farm Y machinery with a tractor I have found that if Jc he proper steering control mechanism can be afforded,- vvthe tractor can be 'steered by ,the manv whoisseated on' the binder, and

My improved steering rod controlling device is designedfor the purpose of enabling [af'mantosit ona binder or other piece of farm machineryand control the steering 'mechanism on attractor located afsubstantial distance "away from the binder.'V

*In theaccompanying drawings,VV I have used' the reference numeral 10 tov indicate generallya steering rod'having onE its upper end the steering wheel 11. The rod it vis understood is; designed to be connectedgwith the steering mechanism of ajtractor.

' My`A improved attachment comprises a steering wheel 12 secured -'to an auxiliary steering rod 13 whichjextends" toward the tractor.V

Y"Near the steering wheel '11 the steering vIOd isprovided with a'number of joints 14 such as those shown in Figs. 6 land 8 inclusive which may be made in any suitable way to permit each portion ofthe steering rod to swing one plane) with relation to the portion to Vwhich it is 'secured'.

" In the' particular form of the joint shown herein, I have shown the-steeringrod V13 provided at one end with a longitudinally profjecting shank -15 which is received between two arms 16 oi ana'djacentmember on the 'Y Fig. 7 shows a view taken at right-angles tothe view shown in Fig. 6, the spring beemployed for maln'ng several joints.

Connected with what might he called the i forward portion of the steering rod, indicated in Fig. 3 by the reference numeral 13a, is a device designed to be secured to the steering wheel 11 comprising a hub 18 having a socket 19 which receives the end of the rod portion'13a and is secured thereto by means of a set screw 20.

Formed on the hub 18 is a series of later-1 .25 f In Fig. 12 I have shown a hollow tubular buckling, so that any .rotation lof the steering rod 13 imparts rotation to the po-rtion 13a, and thence to the wheel 11 and the steering4 ,rodA 10. At the same time the auxiliary steering rod may be bent to various positions for enabling it to be properly extended rearwardly tothe binder or other piece of farm machinery, and for permitting the play of the parts necessary when the tractor or binder is traveling over-rough ground.

- preferred form of my means for fastening 5 The rod 13 rests ufpon a hanger 37 which permits rotation of the rod and @also permits it to swing laterally without binding.

shaft with one of the link members 41 having a reduced extension 42 received in the end of the tubular member and secured thereto by means .of a set-screw v43.

In Fig.9 I have shown what is really the the flexible shaft to the steering Wheel 11.

There isjprovided at the end of the shaft a Vcross bar 44 which is rigidly connected with thefshaftmember 45 on which the spring 26V mounted.A The spring 26 is secured to the y cross bar 44.

- The cross bar V44 has 2 a pair of spaced, longitudinally elongated slots 46. Extended through the slots 46 are'hook bolts 47 having nuts 48 on one end and having hook members 49V adapted to receive the rim of the wheel at thefother end.

On account of the shape of the slots 46 th crossl bar 44 can be readily and reasily fastened to steering wheels of different sizes.

One of the important features of my device is the arrangement of the spring fastened at one end withv relation to the shaft and arr( nged to turn freely with the shaft. The spring must either be fastened at the end Iadjacent to the steering wheel 11 steering wheel for the reason that when the shaft is straight the spring w-ill extend a Y certain distance on the shaft, whereas when the shaft is bent the spring will occupy a greater length on the shaft.

It will be seen that a device of this kind can be readily and easily applied as an at- `tachment, and can be made at a very sin-all expense, and Y'when in use will save the labor of one man. i

In the drawings I have used the reference numeral 131to indicate the sho-rt joint members of the auxiliary steering rod 13.

Some changes may be made in the construction and arrangement of the various 1 parts of my improvedjsteering rod controlling device without departingfrom the essential features and purposes of my invention,

A and it is my intention to cover by my claims anymodiied forms of structure or use `of mechanical equivalents which may be reasonablyjncluded within the scope of my claims.

I claim as my invention:

1. `In a device of the classi described; the combination of a steering` wheel, an auxiliary steering device, ywith a flexible shaft, comprising a plurality` of members pivoted together end to end, with the axesof the alternate pivots lying in planes substantially perpendicular to .fthe yplanes in which the intermediate pivots lie; means for prevent ing buckling of said members; adjustable kmeans at the forward end of said shaft for securing said shaft to the steering wheel; and means for securing said shaft to the auxiliary steering device.

2. In a device of the class described; the combination of a steering wheel, with an auxiliary steering wheel spaced therefrom; a flexible shaft secured :at one end to the auxiliary steering wheel; means at its other end for fastening said flexible shaft to the steering wheel, said means comprising a cross bar on said shaft; `elongated slots in said cross bar; hookbolts extended through said slots, said hook bolts being adapted to receive the rim of the steering wheel for operatively connecting said steering wheel with the auxiliary steering wheel.
